Additional Details

Investigated for the treatment of cancer.
Camptothecin demonstrated strong anticancer activity in preliminary clinical trials but also low solubility and adverse drug reaction. Camptothecin is believed to be a potent topoisomerase inhibitor that interferes with the essential function of topoisomerase in DNA replication.
Mode of Action:
Camptothecin binds to the topoisomerase I and DNA complex (the covalent complex) resulting in a ternary complex, and thereby stabilizing it. This prevents DNA relegation and therefore causes DNA damage which results in apoptosis.
Acute oral toxicity (LD50) in mouse: 50.1 mg/kg
